Clay tiles

Marley Eternit has launched a new range of premium handmade clay tiles. The tiles will be handmade by craftsmen, using locally sourced Etruria Marl. This traditional process includes shaping and pummelling the clay by hand into a mould before being sent for drying and firing. The company said the Canterbury tiles will give a beautifully distinctive handmade finish to the roof. The new tiles will be available in three colours; Chailey (orange), Loxleigh (antique) and Burford (brown) with its own handmade fittings range. Marley Eternitwww.marleyeternit.co.uk

Roof panels

Kingspan has announced that its TEK cladding panels are now available in a new 172mm panel thickness. The cladding panels comprise two layers of oriented strand board type 3 (OSB/3) either side of a high performance insulated core. The company says that the new thicker panels can easily achieve U-values as low as 0.10 W/m2.K, as the system’s proprietary jointing system offers excellent air tightness. The panels are designed and factory pre-cut to each project’s specifications by one of the Kingspan TEK delivery partners.Kingspanwww.kingspantek.co.uk

Slates

Approximately 40,000 fibre cement Westerland slates from Cembrit have been chosen for the Laureate housing development in Devon. Each home is finished in either combination brick or render and roofed with the Westerland slate. The company said the Westerland slate was chosen as it has an attractive riven surface and natural dressed edge, which makes it an ideal solution for situations where a traditional appearance is important. Laureate Heights is a small development consisting of 85 homes situated to the north of Sidmouth.Cembritwww.cembrit.co.uk

Green Roof

Alumasc’s green roof system has been specified for the Buchanan Street development in Glasgow. The green roof system addressed the need for a suitable growing medium to be supplied that could be deposited onto the 5-storey building’s roof in large volumes. This was required as a result of the development being in a busy city-centre location. The company says their green roof system was chosen due to its versatility and ability to be installed quickly on site. Around 2,000m2 of green roof was installed.Alumascwww.alumasc.co.uk

7,500m2 of Knauf Insulation’s Polyfoam ECO Roofboard Extra in 205mm and 220mm and Slimline Membrane has been supplied for the new Woburn Forest Village project at Center Parcs.

The company said the Polyfoam ECO Roofboard was chosen due to its ability to meet the environmental requirements for the project, producing a conductivity value of just 0.033 W/mK across the whole range.Knauf Insulationwww.knaufinsulation.co.uk
